3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Elastic modulus elasticmodulus
The ratio of longitudinal stress to longitudinal strain of rock specimen under uniaxial compression without lateral conditions.
3.2
Deformation modulus deformationmodulus
Under the condition of no lateral direction, the rock stress-longitudinal strain curve obtained by rock specimen under uniaxial compression corresponds to 50% compressive strength.
The slope of the point where the point is connected to the origin, that is, the secant modulus.
3.3
Poisson'sratio
The ratio of transverse strain to longitudinal strain of a rock specimen under uniaxial compression without lateral conditions.
4 Principle
By determining the longitudinal and transverse strain values of rock specimens under uniaxial compression conditions, the rock elastic modulus, deformation modulus and mooring are calculated accordingly.
